EDWARD P. FOLLETT, OF CHICAGO, ILLINOIS.

SHOT-CARTRIDGE.

Application filed May '7. 1909.

Specification of Letters Patent.

Patented Nov. 1, 1914).

Serial No. 494,668.

To all whom it may concern:

Be it known that I, Eowann P. Fonnn'r'r, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Shot-Cartridges, of which thefollowing is a specification.

The object of my invention is to provide a shot cartridge in which aseparate case is secured containing the shot; that, when the cartridgeis fired, leaves the shell, holds the shot inclosed to the distance atwhich it is designed to have the shot leave the case and scatters; acase which with its charge of shot can be placed in the metallic shellof shot and rifle cartridge, which after the fixed charge or bullet hasbeen fired can be reloaded with powder and wads and the case ofshotwhich I call a concentrator be inserted and fired from a gun orrifle; the concentrator being adapted to release the shot and scatter atthe particular distance desired.

The manner in which I accomplish my object is described in the followingspecification and illustrated in the accompanying drawings in which:

Figure 1 is a longitudinal section of the shot cartridge containing theconcentrator. Fig. 2 is a crosssection on the line 22 Fig. 1. Fig. 3 isa sectional view of a rifle shell with the concentrator inserted. Fig. lis one end of the concentrator shown in Fig. 3. Fig. 5 is a section onthe line Fig. 3 of the concentrator.

In the drawings A indicates the shell of the shot and the riflecartridges.

B indicates the concentrator as a whole as shown in the several figures.

0 is the cylindrical part of the concentrator which is made of papergreased to move freely in gun or rifle barrel. When the concentrator ismade to be fixed in a shot cartridge as shown in Fig. 1 one end of thepart C is closed by a metal cap D which is folded and rolled on one endof the cylinder as shown at D Fig. 5. The other end of this cylinder isclosed by a head E made of paper having air holes E When theconcentrator is so formed and partly filled with shot and is insertedwith the cap D against the wads F the end of the shell A is then crimpedinward against the head E thereby completing the shot cartridge as shownin Fig.1. When the concentrator in-epared for use in a metallic shot orrlfle cartridge shell as shown 111 Fig. 3 a fixed metal head G issubstituted for the paper head E. This head G has air holes G and isfolded upon the end of the cylinder and rolled down thereon after theshot is inserted as shown in Fig. 5, thus both ends of the cylinder aresecured and the concentrator is ready for insertion in the metallicshell as shown in Fig. 3. The rolled edges I) of the cap D and head Gtogether with the edges of the cylinder C are pressed below the diameterof the main part of the cylinder as shown in Fig. 5 and are therebyprevented from contact with the interior of a straight or rifled chokedbore barrel. This construction also permits the cylinder 0 to enter thegrooves of a rifle barrel. The holes E and G in the heads of theconcentrator are adapted in number to the particular air pressuredesired in the concentrator after it leaves the muzzle of a gun orrifle.

The air entering the concentrator through. the holes in the headoperates as follows: hen the cartridge is' fired the shot is impelledagainst the cap D and thereby creates the air space between the shot Hand heads E and G as shown in Figs. 1 and As the concentrator leaves thebarrel the air enters and gathers pressure at the cap and the shot whichmoving forward by their weight and by pressure of the air and therebychanges the air space from the front to the rear of the cylinder. Thischange of location of the air space produces results similar to that offeathers on an arrow in keeping the concentrator from turning over. andat the particular distance determined by the construction and of theconcentrator the air pressure in the cylinder retards its flight thehead and shot being thereby released therefrom. When the concentrator isused in a metallic shot or rifle shell the head. being secured to thecylinder, and the movement of the shot and action of the air being thesame, the release of the shot is effected by the bursting of thecylinder at a distance determined by the quantity of air admittedthrough the head and the thickness of the paper of which the cylinder ismade. The pressure of the body of the cylinder G into the rifle groovesgives the concentrator the same rotary movement as a rifle ball, and

together with the rear air space insures a directness and distance inthe firing of shot not otherwise obtained.

What I claim and desire to secure by Letters Patent is:

1. The combination with a cartridge shell; of a shot concentratorinscrtible therein, said concentrator consisting of a cylindrical bodyand ends adapted to close said cylinder, one of said ends nearest theopen end of said cartridge having a plurality of perforationsintermediate of the center and its rim, and a charge of shot partlyfilling said concentrator as described.

2. The combination with a cartridge shell; of a shot concentratorinsertible therein, said concentrator consisting of a cylindrical bodyand abutting ends, said ends being adapted to close said cylinder, oneof said ends nearest the open end of said cartridge having a pluralityof perforations, and a charge of shot partly filling said concentrator,as described.

3. The combination with a cartridge shell; of a shot concentratorinclosable therein, consisting of a cylindrical body and ends adapted toclose said cylinder, one of said ends nearest the charge in saidcartridge being fixed to and closing said cylinder, the other end beingadapted to abutagainst the other end of said cylinder and having aplurality of apertures, and a charge of shot. partly filling saidcylinder as described.

4. The combination With a cartridge shell;

of a shot concentrator scclncd therein, said concentrator consisting ofa cylindrical. body having one fixed end and another end adapted to abutagainst the opposite end, said abutting end being nearest the open endof said cartridge, and having a plurality of perforations, the diameterof said ends being less than the diameter of the central part of saidcylindrical body, and a charge of shot partly filling said concentratoras described.

5. The combination With a cartridge shell; of a shot concentratorinsertible therein, said concentrator consisting-of a cylindrical bodyhaving fixed ends, one of said ends having a plurality of perforationsand the diameter of the central part of said body being adapted toprevent the ends from contact with the barrel of a gun, and a charge ofshotpartly filling said concentrator. i

6. The combination With a cartridge shell; of a shot concentratorinsertible in said shell, and containing a charge of shot, saidconcentrator consisting of a cylindrical body, ends fixed thereon, oneof said ends having a plurality of perforations therein, and an airspace in said concentrator whereby the air entering said body throughsaid perforated end is adapted to discharge said shot from saidconcentrator.
